A) \[\text{3 }km/h\]
B) \[\text{4 }km/h\]
C) \[\text{5 }km/h\]
D) \[{{10}^{-6}}{{m}^{2}}\]
Correct Answer: B
Solution :
As \[{{5}^{2}}+{{12}^{2}}={{13}^{2}}\], so these forces will be acting along the side of a right angled triangle. Angle between 5N and 13N. \[={{180}^{o}}-({{90}^{o}}+{{23}^{o}})\] \[={{67}^{o}}\]You need to login to perform this action.
